In my case it's increased the number of lashes and has certainly lengthened them a lot, rather than coating them. The individual lashes are also thicker. I've used all the application methods - along the lashline, on the lashes and along the lid (variety is the spice of life :wink
and have never had a reaction to the product. My eyes are still blue/grey (
some say their eye colour has changed) but, although my lashes are much thicker and longer, they haven't gone darker as some have said they might.
Consequently, as I'm blonde, I do still wear mascara although I now only wear a single coat.
